Abstract: A system for converting thermal energy to mechanical energy in a vehicle: A line circuit (35), a pump (36) for recirculating a medium in the line circuit, at least one evaporator (31, 32, 38) in which the medium is caused to absorb thermal energy from a heat source (4, 28) so that the medium becomes vaporised, a turbine (39) driven by the vaporised medium in order to generate mechanical energy, followed by a condenser arrangement (24, 42) in which the medium is caused to give off thermal energy so that it condenses. The condenser arrangement includes a first condenser (24) in which the medium gives off thermal energy to coolant which circulates in a cooling circuit, and a second condenser (42) downstream of the first condenser (24) with respect to the medium's direction of flow in the line circuit (35) and in which the medium gives off thermal energy to air at the temperature of the surroundings.

Abstract: In a device for sawing apart two-up blocks (5) of adhesively bound or thread-stitched book blocks and brochures (6a, b), said device having a conveying apparatus for continuously transporting the two-up blocks and the cut-apart book blocks or brochures, which apparatus includes two or more plate-chain conveyers (9a, b) which are disposed side by side, carry the two-up blocks and, optionally, grip behind the latter with the aid of entrainment means (10), and of associated upper pressure-applying belts (12a, b), and said device having a circular saw blade (16) which is driven in a manner rotating in the same direction as the direction of conveyance of the two-up blocks and the axis of rotation of which is disposed above the plane of conveyance of said two-up blocks, an almost smooth separation at high processing speeds is achieved by providing a scoring tool (13) for the underside of the two-up blocks (5) disposed in front of the circular saw blade (16) for the purpose of scoring into the underside with at leas

Abstract: A bucket wheel excavator has a scraper blade mounted on the bogie and whose height is independent of the raising and lowering of the bucket wheel to maintain a level track for the crawler bogie. The scraper blade can be tilted about a horizontal axis by at least one hydraulic cylinder.

Abstract: A bucket-wheel excavator has its bucket-wheel conveyor stopped when a truck is fully loaded so that a new truck can be brought into position, the continuously-operating bucket wheel filling the bucket-wheel chute with a first store of the material. After an empty pass of the dumping conveyor, the bucket-wheel conveyor is driven at a creeping speed and a second store of the material is formed in the receiving chute of the dumping conveyor which is turned onto operate at creeping speed when the material reaches the upper belt drum of the bucket-wheel conveyor belt. Once the empty truck is in position, the belts are accelerated to maximum speed.
